Hetman, Minneapolis, Minn,assig or to De Vac, Inc., Minneapolis, Minn. Filed Feb. 24, 1960, Ser.No. 10,699 6 Claims. (Ci. 20.-52.2)

My invention relates generally to an improvement in windows, moreparticularly to the so-called double hung type and in detail to aremovable friction held or balanced, slidable and releasably lockingwindow sash construction made substantially of extruded aluminum.

It is an object of my invention to provide a cartridge member which isslidably or fixedly mounted within a horizontal rail of a window sashand which is spring urged outwardly for pressing engagement with theinner surface of the frame stile which allows removal of the sash fromthe frame and provides a guided sliding of the sash within the framestile. It is a further object to provide within the same slidablecartridge a spring urged slidable locking pin which is engageable withrecess means formed in the stile for releasably locking the sash inpredetermined positions.

It is still a further object to provide in a further version of thecartridge, which is mounted in the lower horizontal frame rail of theupper sash, a pin member extending transversely from the locking pin andmeans on the upper rail of the lower sash for engaging the pin when bothsashes are fully closed to thereby prevent movement of the locking pinwhereby the sashes are automatically locked when the opposed upper andlower sashes are placed in closed position.

It is also an object to provide the aforementioned cartridge members ofplastic and preferably nylon or the like whereby the end thereof, whichis in pressing engagement with the frame stile, slides in a free butslightly limited manner, thereby giving a guided balance to the sashwithout sagging of the sash on one side or the other. The locking pinmounted therein slides in a free and desirable manner due to the factthat the cartridge is nylon.

It is a further object to position a similar cartridge and locking pincombination aforementioned in the sash at a point opposite to the springurged cartridge carrying a locking pin but with a fixed slidable contactof the end of the cartridge with the frame stile.

I shall not here attempt to set forth and indicate all of the variousobjects and advantages incident to my invention, but other objects andadvantages will be referred to in or else will become apparent from thatwhich follows.

The invention will appear more clearly from the following detaileddescription when taken in connection with the accompanying drawings,showing by way of example a preferred embodiment of the inventive ideawherein like numerals refer to like parts throughout.

FIGURE 12 is an exploded perspective view of the cartridge and boltmechanism together with a portion of the lower rail of the lower sash atthe left end thereof as seen from the inside.

Referring to the drawings in detail, my sash construction A includes thefirst and second side frames or stiles 2t and 22 respectively, which maybe formed of extruded aluminum and which are secured inside conventionalnew window framing or which may be secured in old window framing. Theupper ends of the stiles 20 and 22 are connected to a top frame orlintel member 24, and the lower ends of the stiles 20 and 22 areconnected to the sill member 26. The stile 29 is channel-shaped andincludes the base portion 28, the inner flange portion 30, the outerflange portion 32 and the substantially centrally disposed flangeportion '34. The flanges 30 and 32 mount the weather stripping and sashguide strips 36 and 38 respectively, the strip 36 being mounted on thelower half of the flange 30 and the strip 38 being mounted on the upperhalf of the flange 32. Both the strips 36 and 38 are spaced from thebase 28 to contact the frame of the sash hereinafter described.

Secured to the flange 34 is a channel-shaped non-metallic elongatedguide member 40 formed with the oppositely disposed rib portions 42 and44, the rib 42 being contacteed by the lower inner sash frame 46 and therib 44 being contacted by the upper outer sash frame 48. The guide :40prevents metal to metal contact of the sashes thereby lessening coldconduction and elimination of binding of the parts. The sash frame 46 isprovided with the glass 47 and the sash frame 48 is provided with theglass 49.

The stile 22 is I-shaped and includes the central base portion 5%, theinner flange portion 52, the outer flange portion 54 and thesubstantially centrally disposed flange portion 56 on the base 50. Theflanges '52 and 54 mount the weather stripping and sash guide strips 58and 60 respectively adjacent the base portion 50. The strip 58 ismounted on the lower half of the flange 52, land the strip 60 is mountedon the upper half of the flange portion 5 I also provide thenon-metallic elongated guide member 62, identical to the guide member'40, which is secured to the flange 56.

The lower sash frame 46' includes the lower rail 64, the upper rail 66,and the oppositely arranged stiles 68 and 70. The lower rail 64 issubstantially rectangular in cross section and is formed with aninternal rectangular recess 72 extending throughout the length thereof.Slidably positioned within the recess 72 at the left end thereof, asviewed from the inside of the window, FIGURES 2, 8 and 12, is thecartridge sash holder 74 also referred to as a first cartridge in theoverall picture. The cartridge 74 is urged outwai'dly of the frame 64 bythe primary coil spring 76 for pressing engagement with the stile 20.

The cartridge 74 is positioned within the recess '72 with the inner endthereof up against the spring 76 which further abuts stop screw 7 8. Theslidable cartridge 74 carries the locking pin 80 slidably mounted in therecess 82 of the cartridge 74, and the locking pin 80 is spring urgedoutwardly of the cartridge 74 by the secondary coil spring 8 4 mountedbetween the inner end of the pin 80 and the stop 86. The locking pin 80is moved and its movement limited by means of the release pin 88 securedto the pin 80 and extending outwardly through the slot 90 formed in thewall of the cartridge 74 and the slot 92 formed in the inner wall 94 ofthe lower rail '64. The stile 20 is formed with the spaced holes 96which receive the end of the locking pin 80/ for holding the sash 46 atpredetermined positions. The outward travel of the pin in the cartridge74 is limited by the release pin 88 contacting the stop edge 8-1 of slot90, and the cartridge 74 is prevented from coming out of the recess 72by the release pin 88 contacting the stop edge 83 of the slot 92.

The right hand end of the lower rail 64, looking at FIGURES 2 and 8, haspositioned in the recess 72 thereof the cartridge 98, also referred toas a fourth cartridge in the overall picture, which is secured in fixedposition in the rail 64 by means of the screw 100. The cartridge 98 issubstantially identical to the cartridge 74 and mounts the slidablelocking pin 102 urged outwardly of the cartridge by the coil spring 104.The outer end of the cartridge 98 extends slightly beyond the end of therail 72 for sliding engagement with the base portion 50 of the stile 22.It will be seen that the end of the cartridge 98 is urged against thestile 22 by virtue of the oppositely disposed spring urged cartridge 74held in pressing engagement with the stile 20. The pin 106 is secured tothe locking pin 102 and is used to move the same against the action ofthe spring 104 to remove the end of the pin #102 from one of a series ofholes 108 formed in the base 50 of the stile 22 for locking the sash '46at predetermined positions. The pin 106 extends through the slot 1100fthe cartridge 93 and the slot 112 of the rail 64 for easy access. Theoutward movement of the pin 102 is limited by contact of the pin 106with the stop edge 111 of the slot 110 of cartridge 98 and cartridge 98is prevented trom coming out of recess 72 by contact of pin 106 withstep edge 113 of slot 112. The cartridges 7 4 and 98 are also made ofnylon for the desired sliding frictional engagement of the ends thereofwith the appropriate stile and the surfaces of the recess 72 of the rail46.

The lower sash frame 46 also includes the upper rail 66 which is formedwith the longitudinally extending inner recess 114 which slidablyreceives the nylon sash holder cartridge 116, also referred to as asecond cartridge in the overall picture, which is urged outwardly into,pressing engagement with the stile 20 by means of the coil spring 118which abuts the screw 120. The outward movement of the cartridge 116 islimited by means of the pin 122 secured to the rail 66 and extendingthrough the slot 124 formed in the cartridge 116.

Also positioned in the recess 1114 of the rail 66 is the nylon cartridge126, also referred to as a third cartridge in the overall picture, whichextends slightly beyond the frame and is secured in fixed position bymeans of the screw 128 for pressing engagement with the stile 22 as aresult of the oppositely disposed spring urged cartridge 116.

The upper rail 66 includes the outer lip :13!) used to facilitate theraising and lowering of the lower sash 46. Also formed on the rail 66 isthe top extension portion 132 from which depends the elongated lip 134.The lip 134 has formed therein adjacent but spaced from the outer endsthereof the V-shaped slots 136 and 138 each having the bottompin-receiving slot portion 140 and 142 respectively together with theinsulative contacting strip 144. As the lower sash 46 is lowered to itslowermost position the slot portions 140 and 142 of the lip 134 of therail 66 receive the stop pins 146 and 148 secured to the locking pins196 and 166, respectively, to thereby lock the upper sash 48 bypreventing movement of the pins 146 and 148 and consequently the pins1-96 and 166, as hereinafter described.

The upper sash frame 48 includes the lower rail 150, the upper rail 152,and the oppositely arranged stiles 154 and 156. The rail issubstantially rectangular in cross section and is formed with theinternal rectangular recess 158 extending throughout the length thereof.Slidably positioned Within the recess 158 at the left thereof as viewedin FIGURE 7 and also in FIGURE 10 and again in FIGURES 4 and 5, is thecartridge 160, also referred to as a fifth cartridge in the overallpicture. The cartridge 160 is urged outwardly for pressing engagementwith the base 28 of the stile 20 by means of the primary spring 162which abuts the screw 164. Slidably mounted within the cartridge 160 isthe locking pin 166 which is urged outwardly of the cartridge 160 bymeans of the secondary spring 168. The outer end of the locking pin 166engages three holes 170 formed in the base portion 23 of the stile 20.The pin 148 is connected to the locking pin 166 and extends outwardlythrough the slot 171 of the cartridge 160 and the slot 172 formed in thewall 174 of the rail 150 and also outwardly through the slot 176 of theupstanding lip 178 which is connected to the extension portion 130connected to the wall 174 of the rail 150. The lip 178 mounts theinsulating strip or gasket 179, and when both sashes are closed, theinsulating strip 144 contacts the lip 173 and the insulating strip 179contacts the lips 134 to seal the two sashes together.

The numeral 182, particularly FIGURES 4, 7 and 9, designates avertically disposed actuating pin which is connected to the locking pin166. The pin 182 extends downwardly through the slot 13-4 of thecartridge 160, and the slot 186 of the rail 150. The outward movement ofthe pin 166 is limited by contact of the pin 132 with the stop edge 188of the slot 184 and the cartridge 160 is restricted in its outermovement by the pin 182 contacting the step edge 190 of the slot 136 ofthe rail 150, FIGURES 4 and 9.

Further provided in the rail 150, particularly FIGURES 3, and the rightof FIGURE 7, and the left of FIGURE 9, is the cartridge 192, alsoreferred to as an eighth cartridge in the overall picture, which isfixedly mounted in the recess 158 by means of the screw 194. The outerend of the cartridge 192 extends slightly beyond the rail 150 toslidably contact and also make pressure engagement with the stile 22 dueto the spring action of the cartridge 160 oppositely disposed tocartridge 192. Slidably mounted within the cartridge 192 is the lockingpin 196 which is urged outwardly of the cartridge 192 by means of thecoil spring 198 into one of a series of holes 200111 the stile 22.

Secured to the locking pin 196 is the horizontally disposed pin 146which extends outwardly through the slot 202 formed in the wall of thecartridge 192, the slot 204 of the wall 205 of the rail 150 and throughthe slot 206 of the upstanding lip 178 formed on the extension portion183 gonnected to the rail 150, particularly FIGURES 3 an The numeral212, FIGURES 3 and 9, designates a vertrcally disposed actuating pinwhich is secured to the locklng pin 196 and extends downwardly throughthe slot 214 formed in the cartridge 192 and also through the slot 216formed in the bottom wall 218 of the rail 150. The extent of the outwardmovement of the locking pin 196 is limited by the contact of the pin 212against the end shoiulgder 220 of the slot 216, particularly FIGURES 3an The upper rail 152 of the upper sash 48 is substantially rectangularin cross section and formed internally and longitudinally thereof is therecess 222, FIGURES 2 and 6. Looking at the left of FIGURE 6 inparticular, we find the cartridge 224, also referred to as a sixthcartridge in the over-all picture, which is slidably mounted in therecess 222 and spring urged against the base 28 of the stile 28 by meansof the spring 226 which abuts the screw 228. The cartridge 224 hasformed therein the transverse slot 221 through which extends the pin 223secured to the rail 152. The pin 223 allows movement of the cartridge,but prevents it from coming out of the recess 222, FIG- URES 2 and 6.

Further provided is the cartridge 229, also referred to as a seventhcartridge in the over-all picture, which is secured in the recess 222'by means of the screw 238 and which extends slightly beyond the rail152 for pressure engagement with the base 50 of the stile 22 due to thespring urged cartridge 224 oppositely disposed.

It will be noted briefly in review that each sash is slidably heldwithin the stiles 28 and 22 by means of four cartridges. The lower sash46 is mounted by means of the opposed lower cartridges 74 and 98, and isopposed upper cartridges 116 and 126. The upper sash 48 is mounted bymeans of the lower opposed cartridges 160 and 196 and the upper opposedcartridges 224 and 229. The detailed construction of each of thecartridges has been hereinbefore set forth, and each is simply mouldedof nylon. The cartridge made of nylon allows 1) easy sliding of the samein its recess where that is the case, (2) easy sliding of the lockingpin within the cartridge and (3) the end of the cartridge has adesirable sliding engagement with the stile.

With both sashes in full closed position; that is, with the lower sash46 in fully lowered and locked position and the upper sash 48 in fullyraised and locked position, the locking pins 81) and 162, FIGURE 8, ofthe lower rail of the lower sash 48 are in engagement with the holesformed in the stiles and 22 respectively, and the cartridges 74 and 98in pressing engagement with the stiles 2E) and 22 respectively. At thesame time, the upper cartridges 116 and 126 of the upper rail 66 of thelower sash 46 are in pressing engagement with the stiles 28 and 22respectively. In addtion, the locking pins 166 and 196, of the lowerrail of the upper sash, FIGURES 3, 4, 5 and 7 are in engagement withholes 170 and 2% respectively of the stiles 2t) and 22 respectively withthe ends of the cartridges 160 and 192 in pressing engagement with thestiles 20 and 22 respectively. In addition, the pins 146 and 148 are inengagement with the slots 140 and 142, respectively, of the lip 134 andas a result the locking pins 166 and 196 cannot be moved thereby lockingthe upper sash 48 in full raised closed position and thereby preventingmovement of the upper sash until the lower sash is raised. At the sametime, the cartridges 224 and 229 in the upper rail 152 are in pressingengagement with the stiles 2i) and 22 respectively.

To raise the lower sash 46 the release pins 88 and 106 are movedinwardly of the window thereby withdrawing the lock pins 8!) and 182respectively from the holes in the stiles 20 and 22 respectively. Itwill be noted that as the pins 80 and 102 are slidably moved inwardly toclear the holes of the stiles the cartridges remain in pressingengagement with the stiles.

To lower the upper sash 48 from upper locked position, the lower sash 46must first be raised sufficiently to move the slots 140 and 142 of theflange 134, FIGURE 9, out of engagement with the pins 146 and 148respectively. Then the pins 182 and 212 may be moved to thereby withdrawthe locking pins 166 and 196 respectively from the holes 170 and 208respectively in the stiles 20 and 22 respectively, and in this conditionthe ends of the cartridges 160 and 192 respectively are still inpressing engagement with the stiles 20 and 22, respectively. With thelocking pins 166 and 196 withdrawn, the upper sash may then be lowered.As the upper sash is lowered, the cartridges 224 and 229 are in pressureengagement with the stiles 20 and 22, respectively.

It will be seen that as the lower sash is lowered and locked the uppersash is automatically locked when in full raised position.

All of the eight cartridges 74, 98, 116, 126, 160, 192, 224 and 229 areformed of plastic, preferably nylon and due to the nature of thematerial, the contact of the ends of the various cartridges with thestiles allows a sliding, but restrained movement, thereby providing thedesirable friction hold of the sashes. The pins slide in a desirablefashion within the cartridges, and the cartridges slide in a desirablefashion in the rail recesses.

My various cartridges and the construction thereof allow removal ofeither sash 46 or 48 in the following manner: To remove the lower sash46 the same is unlocked and raised slightly to remove the pins 146 and148 from the slots and 142 and by manipulation the entire sash is pushedto the left, FIGURES l, 2, 6-8, against the action of the springs 76 and118 enough so that the outer ends of the fixed cartridges 98 and 126 maybe caused to by-pass the vertical inner edge of the flange 52.

To remove the upper sash 48, the lower sash 46 is raised sufiiciently toremove the pins 146 and 148 from the slots 140 and 142 respectively andby manipulation the entire sash 48 is pushed to the left, FIGURES l, 2,6-8, against the action of the springs 162 and 226 enough so that theouter ends of the fixed cartridges 192 and 228 may be caused to by-passthe vertical inner edge of the flange 54. To insert the sashes, theprocedure is, in effect, reversed. As the lower sash 46 is moved up anddown, it has sliding contact with the shoulders 42 of the guide members40 and 62 and the strips 36 and 58. As the sash 48 is moved up and down,it has sliding contact with the shoulders 44 of the guide members 40 and62 and the strips 38 and 60. When the lower sash 46 is in full lowerlocked position, it is in contact with the sill member 26, and when theupper sash is in full raised and locked position it is up against thetop frame or lintel 24.

The invention is not to be understood as restricted to the details setforth since these may be modified within the scope of the appendedclaims without departing from the spirit and scope of the invention.
